Application filed July 25,

ln the specification of my said main appliy cation improved parquetry plates are .de-

scribed wherein they support for the veneers that are assembled to constitute the parquetry design, consists of a grid composed of parallel battens upon whichthe veneers assembled to constitutel the plate, are glued, the ends of said grid battens.pro-l jecting on all sides beyond the total surface of the veneers. These parqu'etry plates are laid in accordance with the said main application inv the formed between the parquetry veneers when the plates are laid side by side, are filled-in with parquetry strips which cover the .butt joints of the adjacent grid hatten ends. l

The present invention consists in a con;v strurctional application of the idea upon which the improved parquetry of my said main application is based, t parquetry-slat iiooring. y j f According to the present invention strips of parquetry flooring, each comprising one or more longitudinal rows of parquetry slats, are manufactured away from the site (place of use) in a factory by arranging short battens of determined length parallel to one another in one or more rows having a length of 1.5 to 3 metres at clear distances apart of 1 to 2 centmetros, preferably with the use of a template or a jig, so as to form a long grid upon which the said slats are glued. The said slats are arranged at 450 to the direction of the length of the grid, in such a manner that the apeXes of the right-angled free ends of the parquetry slats are flush at both sides with the ends of the grid battens.

The fixing of these strips upon theunderlioor at the site is eected by nailing the grid hatten ends (which project beyond both sides of the slatparquetry) down to the under-floor, and filling the square reeesses that have been left vacant between manner that the channels f 1923.

the yjuxtaposed strips, with square wooden plates. hereinafter referred to as wood squares, having the same thickness as that ofthe parquetry slats.

rlhis'improved method renders it possible to execute the greater part of the work connected with the manufacture of a parquetry slat floor, in workshops furnished with every appliances for accurate worlnnanship, and to limit the work to be done at the site mere-ly to the nailing down of the parquetry floorstrips and the gluing-in of the squares. This improved construction allows therefore of producing an absolutely tight parquetry slat floor which is absolutely faultless as. regards l design, i and whereof the oost of manufacture is considerably less than that of constructions hitherto known. Y

fr floor according to the present invention is illustrated by way of example in the accompanying drawings in which: j

Figures l and 2 are respectively a plan and a cross section taken along the line A-v-.l-i of Figure l, of a parquetry flooring strip comprising a single row of parquetry slats. f

K Figure 3 is a plan of a portion of animproved iioor composed of ksuch strips, in a partly finishedA condition.

Figure l is a section takenalong the line B-"B of Figure 3. .Y

Figure 5 shows a parquetry flooring strip consisting of two rows of parquetry slats arranged at right angles to one another.

Figure 6 is a cross section taken along the line C-C of Figure 5.

Figure 7 is a plan showing in a partly finished state a portion of a parquetry floor constructed of the parquetry flooring strips shown in Figures 5 and 6.

In the manufacture of the improved pa-ry quetry iiooring strips illustrated in Figures l and 2, a grid composed of short battens m is first prepared, preferably with the aid ofthe templates or jigs, and the parquetry slats a are glued upon the battens m` at 45 to the lengthwise direction of the latter. The flooring strips thus produced are piled upon one another and maintained under pressure until the glue has become com pletely dry. battens m are so chosen, in accordance with thelength and width of the'V slats a, that the ends of the said battens willfbe-fl-ush with the' The dimensions of the gridy practical construction of an improved g right-angled free corners z' of the parquetry slats a, so that the ends ot' the grid battens m are exposed or project on both sides of the slot corners z'.

The length ot the flooring strips may be as much as 3 metres, and is so chosen, that when two strips are placed together end to end (as shown at x-x in Figure 3) the incomple-te slats oit one strip will be continued by the complementary slots ot the second strip so as to form composite slats of the proper lengths.

ln laying these prepared flooring strips at the site, they are fastened by nailing to the under-floor, one or two nails t being driven into each of the exposed portions of each grid hatten end projecting beyond the sides of the corners e' oi' the parquetry slats a. In this manner the flooring strips are fixed at each width of a slat a by means of two or 'four nails to the under-floor. The laying of the adjacent Hooi-infr strip along the width of the already laid strip (F ig. 3) is effected in the same manner viZz-the free corners z' of the slats a, arevcaused to abut together exactly, thereby toi-ming a free square recess 0 between every two pairs of abutting slats a, (F ig. 3). After the flooring strips have been fixed to the underloor, these recesses 0 are filled-in with wood squares n which are glued upon the exposed ends of the grid battens, and weighted until the glue has set. In this manner a parquetry slat floor is produced, the ornamental appearance of which is heightened by the occurrence of the illing squares n.

Figures 5 and 6 are respectively a plan and a cross section taken along the line 0*@ of Figure 5, et an improved Hooring strip composed of two rows oi parquetry slats. The manufacture of this Hooring strip is executed in the same manner as described with reference to Figures l to 4. with the sole diitcrence that the length of the grid battens m is twice as great as that used for the manufacture of the flooring strips shown in Figures 1 to t.

A floor (Fig. 7) made up of two-row flooring strips (such as that shown in Figures 5 and 6) differ from the floor illustrated in Figures 3 and et, which is made-up of one-row flooring strips (such as that shown in Figures l and 2) in this that the filling Wood squares n occur only between the pairs of two-row flooring strips.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what l claim is 1. A flooring comprising a long flooring strip composed ot' grid battens arranged at right angles to the longitudinal direction oic said strip, and parquetry sla-ts glued side by side on said grid battens at an angle of to the lengthwise direction of the latter in such a manner that the grid-hatten ends project beyond the free corners of the parquetry slats.

2. A parquetryslat iioor composed of iinproved flooring strips as claimed in claim l, laid upon the ordinary under-floor the projecting ends of the grid bat-tens being nailed down to the under-floor and wood squares being' glued in the recesses occurring at the slat ends ot' adjacent rows ot juXtax posed flooring strips over the exposed portions o'l the grid battens.

In testimony whereof I affix my signature in presence of two witnesses.
